Integrated service equipment for electronic information communication

Abstract

The invention relates to an integrated service equipment for electronic information communication. At present, most dynamic environment monitoring systems adopt a star topology structure mode, a linear chain mode, a special line mode or a 2M time slot pumping (daisy chain mode) networking mode, and have the shortcomings of no separation of monitoring data and business network, large transmission resource occupation, large maintenance workload, high construction cost and the like. The invention is the integrated service equipment DTS8-1A based on the networking mode of multiplex self-healing loop; when an E1 line breaks down, disabled data communication can be automatically switched to the other side to be transmitted to protect transmitted data; when the line restores, the line can automatically switch back. The transmission system comprises a 2M loop circuit data transmission system DTS8-2 (central equipment) and DTS8-1A (node equipment) to realize the function that far-end serial port data is transparently transmitted to the monitoring center and is converted into an IP packet. The integrated service equipment has wide application range, is safe and reliable and is favourable for popularizing.

Description

technical field [0001] The invention relates to electronic information communication equipment, in particular to a comprehensive service equipment integrating FPGA application, Ethernet transmission, E1 transmission and asynchronous serial port communication. Background technique [0002] At present, most power environment monitoring systems adopt star topology, direct chain, dedicated line or 2M time slot (daisy chain) networking methods. These networking methods have different shortcomings. For example, if a direct-chain networking method is adopted, when a device of a certain node fails, all nodes connected to the device may be paralyzed, resulting in serious consequences; while a dedicated line networking method is used, although monitoring transmission is guaranteed. It is stable, but it takes up too many resources and the input cost is too high. Therefore, the current networking mode of the power environment monitoring system has disadvantages such as the inseparabili...

Problems solved by technology

For example, if a direct-chain networking method is adopted, when a device of a certain node fails, all nodes connected to the device may be paralyzed, resulting in serious consequences; while a dedicated line networking method is used, although monitoring transmission is guaranteed. stable, but it takes up too many resources and the input cost is too high

Therefore, the current power environment monitoring system networking method has disadvantages such as inseparable monitoring data and business network, occupying more transmission resources, heavy maintenance workload, and high cost.
